The operation principle of the gear of single wheel drive three speed change gear is in the present invention：Central shaft 1 is power input in the present invention,
Wheel hub 2 is power output member, and during bottom gear, pallet piece 31 is meshed under the control of spring with the first ratchet 32, and power is in
Heart axle 1 is inputted, because central shaft 1 is fixedly connected with the first planet carrier 41, therefore the synchronous axial system of the first planet carrier 41, due to first
Ratchet 32 is arranged on the first planet carrier 41, and the first ratchet 32 is meshed with pallet piece 31 again, and pallet piece 31 is arranged at ratchet again
On part frame 30, thus the synchronous axial system of pallet piece frame 30, due to being connected between pallet piece frame 30 and wheel hub 2 by spline, thus it is dynamic
Power is ultimately transferred to wheel hub 2 and carries out power output by wheel hub 2.During middle speed gear, mobile pallet piece frame 30, makes pallet piece frame manually
Pallet piece 31 on 30 is disengaged from the first ratchet 32, and is meshed with the second ratchet 33, and power is inputted by central shaft 1, by
It is fixedly connected in central shaft 1 with the first planet carrier 41, the synchronous axial system of the first planet carrier 41, the first planet carrier 41 passes through the first planet
The transmission of wheel 42 imparts power to the first gear ring 43, because the second ratchet 33 is arranged on the first gear ring 43, the second ratchet 33
It is meshed again with pallet piece 31, pallet piece 31 is arranged on pallet piece frame 30 again, therefore the synchronous axial system of pallet piece frame 30, due to spine
Connected between bluff piece frame 30 and wheel hub 2 by spline, therefore power is ultimately transferred to wheel hub 2 and carries out power output by wheel hub 2.
During top gear, mobile pallet piece frame 30, makes the pallet piece 31 on pallet piece frame 30 be disengaged from the second ratchet 33 manually, and with
3rd ratchet 34 is meshed, and power is inputted by central shaft 1, because central shaft 1 is fixedly connected with the first planet carrier 41, therefore first
The synchronous axial system of planet carrier 41, the first planet carrier 41 imparts power to the first gear ring 43 by the transmission of the first planetary gear 42, by
It is integrally formed in the first gear ring 43 with the second planet carrier 51, therefore the synchronous axial system of the second planet carrier 51, the second planet carrier 51 passes through
The transmission of second planetary gear 52 imparts power to the second gear ring 53, because the 3rd ratchet 34 is arranged on the second gear ring 53, the
Three ratchets 34 are meshed with pallet piece 31 again, and pallet piece 31 is arranged on pallet piece frame 30 again, therefore synchronous turn of pallet piece frame 30
Dynamic, due to being connected between pallet piece frame 30 and wheel hub 2 by spline, therefore power is ultimately transferred to wheel hub 2 and carried out by wheel hub 2
Power output.
In summary, not only compact conformation after the gear speed change gear of single wheel drive three in the present invention, gearshift manipulation it is convenient and
And gearshift stability is also greatly promoted, the pawl type gearshift in the present invention is also used as freewheel clutch and used in addition,
Without reusing freewheel clutch in planetary transmission, therefore it enormously simplify structure.
The principle and its effect of the above embodiments only illustrative the invention, and the implementation that part is used
Example, not for the limitation present invention；It should be pointed out that for the person of ordinary skill of the art, not departing from wound of the present invention
On the premise of making design, various modifications and improvements can be made, these belong to protection scope of the present invention.
